1 ooAii-eAsaNn OXYGEN BURNER;

Application filed February The object of my present invention,broadly stated, is to provide a construction consisting of an attachment for furnaces, or other heating plants, particularly coal-burning lfurnaces or the like, to provide a hot-blast for producing proper combustion of the fuel and .of theV gases emanating therefrom, whereby every unitof the product .of combustion will be utilized in the production of usable heat, and at thesame time eliminating the production of smoke and soot, and the escape of unburned gas,.and also requiring'less fuel for producing a given amountof heat and by von the line 5-5 of Fig. 2.

which the residue or ash will be reduced to aconstruction, notV subject to deterioration, inlvolving no relatively moving parts after being adjusted, easily installed without damage to 'or previous preparation of the furnace therefor, which can be installed at a minimum of yexpense VandV which can be manufactured and sold at a comparatively low price.

Other particular objects and advantages will suggest lthemselves in the course of the following descriptiom l The preferred means for carrying out the principles of my invention in a practicalmanner is shown in the accompanying drawings,

In the drawings letter A denotes la furnace i door which, in this instance, of slot openings B formed which are usually damper, not shown. V

The invention includes" al pan-shaped, oblong, member forming an air reservoir, and it consists of afla't wall, or bottom, 1 having integral therewith aflangeQeXtending outward. atan anglev and entirely surrounding the edge of the wall 1'.k VThe edge of the Vflange 2 is adapted to Contact againstthe innerl side of the door A," whereby all of the'slots B will be covered thereby and which, together with the inner face ofthe door,ff`orms a chamber3,"with all ofthe openings B leading thereinto from the outside. In the-center 0f the wall 1 a comparatively large aperture is provided, around which a ,collar 'tfis formed integralwith the wall 1, and' extending in` ward therefrom. i

Numeral 5 denotesA the first right-angular,

has a plurality therethrough,

controlled by a .sliding .ToY

or L-shaped, tting which is of the Vsame dij amet'er throughout and without' flanges or threads on either of its ends. llhe longer end portion ofthe iitting 5'is adapted toV slide snugly intoi said collar 4t and the wall 1. A chine or ridge Gis formed around circumferentially on land near the center of the longer portion p of the fitting 5, to engage the inner yend of the collar 4, wherebythe 'fitting 5 is prevented from contacting withI the door A when the iitting 5 is placed iiijsaid collar 4f. Four equally divided apertures 7 vare,` formed through thewall of the o'uterjendportion of y the fitting 5, for the purpose hereinafter 'made apparent.' Two hook-bolts, 8 and 9,''are`provided, eachy having a hook, 10 and 11 respectively, fo'rmed by their vinner end-portions, with their outer portions threaded, andvprovidedwith ythe respective nuts 12 and 13.l i

N ear the juncture of the hooks with the body of their respective bolts, a lug, ltand 15, respectively, is formed, for the purpose hereinafterl set' forth. 'l

ring or washer 16, which is adapted tocon- `tact with the outer side of the door A. Nu- Y I -merals 17 and 18"denote standards which eX- tend outward substantially paralleir with each other from the ring 16, with rwhich they are A 10.0 rllhe exterior bracket comprisesa circfularf,v

has two, spaced apart, slotted apertures, a and i5, formed therethrough in which said bolts 8 and 9 may vfreely operate as desired.

In order to assemble the parts above mentioned one has first to bring the air-box or pan-shaped member to position against the inner face of the door A. The fitting 5 'is then inserted to the position in which it is shown in Figs. 2 and 3. `The hook portions of the bolts Sand 9 are then inserted through slots B of the door and the hooks 10 and 11 are then engaged into two of the oppositelyfdisposed apertures 7, as in Fig. 3, with the boltsl extending outward through slots B. rlhe said bracket Iis then placed against the outer face of the door A, with the aperture in the ring 16 concentric with the inserted end of tliefitting 5. l/Vhile bringing said bracket to position, the outer ends of thebolts are entered through therespective apertures, a and, in

the lcross-bar 19. The next operation is to run the nuts 12 and 13 onto the projecting end portion of the bolts 8 and 9. Now by simply tightening saidnuts against the cross-bar 19 it is evident that all of said parts will be securely clamped linto rigid position in connection with the door A, as the chine 6 will contact with the vinner end of the collar 4f, whereby preventing the member 5 from being drawn outward.

The next element Y employed in this construction is the U-shaped fitting 20, one of its ends terminating in a flange 21 whichis Aadapted to receive therein the upturned end of thefitting 5, where it may be locked byA means 'of the set-screw 22, or otherwise.

The next element in the construction is the L-shaped fitting 23, which may be termed the nozzle member, and its upturned shorter portion terminates in a collar 24, which'is adapt- 4 edv tol receive the outer down-turned end of the member 20, where vit is secured by the setscrew 25. The projecting or inner end of i vthe fitting 23 terminates in a'rounded or hemispherical nozzle portion .26, which is cut by two slots, c, and d, crosswise of. each other, as in Fig. 4.

rllhe members 5, 2O and 23 are all tubular, and' they are made adjustable in order thatA they made be arranged to meet various conditions, as for instance the member 5 may be turned from the position shown simply changing the hooks 10 and 11 to the other pair of apertures 7; by loosening the set-screwv 22 the member 20, carrying with' it the member 23, to vany angle desired; and likewise by loosening the setscrew 25 the member 23 may be swung to any anglevdesired; or a combination of said adjustments may be made.

The arrangementof my device is such that the main portions thereof are located inside fthe combustion chamber of the furnace, with the nozzle'above and directed into orl toward the center of the fire and therefore all parts thereof will become very hot. Then if all before they can pass away,`for the reason that Ithey will be supplied with the proper amount of supereheated oxygen which will cause them to burn with greatintensity and deliver the maximum of heating'y units. By reason of the above every unit of heat in the fuel rwill be converted into usable heat rand thereby accomplishing the objects of my invention ina simple, practical, scientilic, and highly etlicient manner.

it is to 'be understood that my device is not to be limited to a furnace dooror even to a furnace, in the common acceptation of that term, as it may be employed with any kind of wall or partition. Neither is it lim,- ited to the slots B, as shown, as it'may be Vused with a single round or other shaped aperture in the door or partition. Neither is the device to be limited Vto the use vof set-V screws for retaining the fittings in adjusted position, for that purpose. And in place of the outas other meansmay be employed side bracket I have shown itis evident that details of construction from thatzshown with- Y out departing from the spirit of the invenioo ies

tion and without sacrificing anyof the ad vantages thereof ,which are new and useful.

l-laving now fully shown andidescribed' my invention, what l claim, and desire to secure. by Letters Patent of the United States, is-l .1'. An attachment for the purpose set forth comprising, in combination withL a partition having an aperture therethrough, an air 'chamber contacting with the innerY faceof said partition with said aperture opening iio therei'nto, an L-shaped fitting havingY `one f end thereof'located inv said air c hamber with Yits other end located inwardtherefrom, an L-shaped nozzle-fitting spaced from andv in .alinement with said first fitting, a U-shaped fitting connecting the two L-shaped fittings and an airl distributing nozzle formed on the discharge end of said nozzle-litting, substantially assetforth.
